While I really like so much about Modern20. And I find every change from the core d20 to be a major upgrade. There is still a few hold overs from the d20 system I really don't like. As I stated before these are not really concerns any d20 player would even notice. Hit point and feat bloat are two things I just don't like. But still I find it excessive for characters to go into the hundreds of hit points and dozens of feats.
I could never really put my finger on a fix until I started running Castles and Crusades. Some one pointed to the idea of limiting advancement, And the concept behind Epic 6 (which I wrote about here). The idea that since most people are level 1 or even level 0 goons, level 6 is very heroic from that point of view. Even most literary heroes are level 6 or less. (More info on Epic6 wiki).
The only change I would make is in the original Epic 6 characters still gain Exp and still gain feats every time they gain enough Exp to gain a level. I would instead say exp and level still advance but all level dependent bonuses as well as feats stop at level 6. And only skill points are still gained beyond level 6.
I'm not totally convinced level 6 is the right cut off either. It worked fine for C&C but I kind of wonder if Level 10 would not be a better stop point and just end all advancement there. Still a lot to think about.
For the second part of this post I thought I would share with you a statement by Charles Rice, Author of Modern20. As to the reason for making Modern20.
"Modern20 was where I really tried to go far afield. I had been writing and running modern games since 2001 and had seen them all- Spycraft, Call of Cthulhu d20 and so on.
I really decided to take a different path- instead of trying to make "modern archetypes" like Spycraft I took a different approach- your character is class is about HOW you do what you do, not what you do.
Thus you can have Vic Mackey (from the Shield), Pembleton (from Homicide), or Goren (from Law and Order: Criminal Intent).
Mackey is an intimidating thug (Tank), Pembleton walks into the box and gets you to ADMIT what you did (Star) and Goren uses obscure science and psychology to find a killer by getting inside his head (Brainiac).
And yet, they're all detectives.
D20 modern tried to solve this dilemma with a half measure, through the basic class. In d20 Modern parlance Mackey would be a Tough Hero/Detective, Pembleton would be a Charismatic Hero/Detective and Goren would be a Smart Hero/Detective.
However, I didn't think that went far enough, even with the addition of occupations."
